Reproduction Example/SDK Setup
import { DurableObject } from "cloudflare:workers";
import * as Sentry from "@sentry/cloudflare";
class MyDurableObjectBase extends DurableObject<Env> {
constructor(ctx: DurableObjectState, env: Env) {
super(ctx, env);
}
async sayHello(name: string): Promise<string> {
throw new Error("Should be recorded in Sentry.")
}
}
export const MyDurableObject = Sentry.instrumentDurableObjectWithSentry(
(env: Env) => ({
dsn: "__YOUR_DSN__",
tracesSampleRate: 1.0,
debug: true
}),
MyDurableObjectBase,
);
export default {
async fetch(request, env, ctx): Promise<Response> {
const id: DurableObjectId = env.MY_DURABLE_OBJECT.idFromName("foo");
const stub = env.MY_DURABLE_OBJECT.get(id);
const greeting = await stub.sayHello("world");
return new Response(greeting);
},
} satisfies ExportedHandler<Env>;Steps to Reproduce
- Send fetch request to a worker instrumented with
Sentry.instrumentDurableObjectWithSentrywhere the Durable Object RPC method throws when called by the worker. (see example above) - No Sentry logs (console) / errors are recorded.
Expected Result
Sentry should record errors thrown according to the docs
Additionally, since debug: true is set, there should be debug logs from the Sentry library.
Actual Result
No debug logs visible, no errors reported to Sentry.

I'm going to pass this off to @timfish given he's been touching cloudflare stuff recently and I don't have time to follow up - could you take a look?

I have the exact same issue except with Cloudflare Workers, traces are working fine, but my thrown errors aren't appearing in issues. Set it up just now using the Configure Cloudflare Workers SDK docs on a new Cloudflare Workers project.

On the new version, we are now getting the error:
The RPC receiver does not implement the method "METHOD_NAME".This appears locally and in production. See: cloudflare/workerd#4499
